- Behind video lectures in a MOOCPublication . Soares, Filomena Baptista; Lopes, Ana Paula; Vieira, IsabelThe year 2012 was the “boom year” in MOOC and all its outstanding growth until now, made us move forward in designing the first MOOC in our Institution (and the third in our country, Portugal). Most MOOC are video lectured based and the learning analytic process to these ones is just taking its first steps. Designing a video-lecture seems, at a first glance, very easy: one can just record a live lesson or lecture and turn it, directly, into a video-lecture (even here one may experience some “sound” and “camera” problems); but developing some engaging, appealing video-lecture, that motivates students to embrace knowledge and that really contributes to the teaching/learning process, it is not an easy task. Therefore questions like: “What kind of information can induce knowledge construction, in a video-lecture?”, “How can a professor interact in a video-lecture when he is not really there?”, “What are the video-lectures attributes that contribute the most to viewer’s engagement?”, “What seems to be the maximum “time-resistance” of a viewer?”, and many others, raised in our minds when designing video-lectures to a Mathematics MOOC from the scratch. We believe this technological resource can be a powerful tool to enhance students' learning process. Students that were born in digital/image era, respond and react slightly different to outside stimulus, than their teachers/professors ever did or do. In this article we will describe just how we have tried to overcome some of the difficulties and challenges we tackled when producing our own video-math-lectures and in what way, we feel, videos can contribute to the teaching and learning process at higher education level.
- Developing multiple - choice questions in mathematicsPublication . Torres, Cristina; Lopes, Ana Paula; Azevedo, Jose Manuel; babo, lurdesIn this paper we wish to illustrate different perspectives used to create Multiple-Choice questions and we will show how we can improve these in the construction of math tests. As it is known, web technologies have a great influence on student’s behaviour. Based on an on-line project beginning at 2007 which has been contributing to help students on their individual work, we would like to share our experience and thoughts with colleagues who have a common concern when they have the task of constructing Multiple-Choice tests. We feel that Multiple-Choice tests play an important and a very useful supporting role in selfevaluation or self-examination of our students. Nonetheless, good Multiple–Choice Test Items are generally more complex and time-consuming to create than other types of tests. It requires a certain amount of skill. However, this skill maybe increases through study, practice and experience. This paper discusses a number of issues related to the use of Multiple-Choice questions, lists the advantages and disadvantages of this question format contrasting it with open questions. Some examples are given in this context.
- How to teach mathematics with MOODLEPublication . Torres, Cristina; Azevedo, Jose Manuel; Lopes, Ana Paula; babo, lurdesThe aim of this article is to present a Project in the Oporto’s Institute of Accounting and Administration, which pretends to contribute for a change in the way of teaching and learning Mathematics. One of the main objectives of this project is to innovate the teaching and learning processes, exploring technologies as a pedagogical resource and to induce higher motivation to students, improve the rate of success and make available to students a set of materials adapted to their needs. This concern is justified due to the fact that students have a weak preparation, without consolidated basis. Since the year 2007/2008 the courses were adjusted to the Bologna process, which requires several changes in teacher’s and student’s roles, methodologies and assessment. The number of weekly classes has been reduced, so it was necessary to develop new strategies and methodologies to support the student. With the implementation of the Bologna Process in the Accounting degree, we felt a great need to provide other types of activities to students. To complement our theoretical and practical classes we have developed a project called MatActiva based on the Moodle platform offered by PAOL - Projecto de Apoio On-Line (Online Support Project). Moodle allows us to use the language TEX to create materials that use mathematical symbols. Using this functionality, we created a set of easy to use interactive resources. In MatActiva project, the students have access to a variety of different materials. We have followed a strategy that makes the project compatible with the theoretical and practical subjects/classes, complementing them. To do so, we created some resources, for instance multiple-choice tests, which are the most accessed by the students. These tests can be realized and corrected on-line and for each wrong answer there is a feedback with the resolution. We can find other types of resources: diagnostic tests, theoretical notes. There are not only the pre-requirements for subjects mathematics, but also materials to help students follow up the programs. We also developed several lessons. This activity consists of a number of pages, where each page has contents and leads to other pages, based on the student's progress. The teacher creates the choices and determines the next page that the student will see, based upon their knowledge. There is also an area of doubts, where the students can place all the mathematical doubts they have, and a teacher gives the answers or clues to help them in their work. MatActiva also offers an area where we can find some humour, curiosities, contests and games including mathematical contents to test the math skills, as well as links to pages about mathematical contents that could be useful for the study. Since ISCAP receives ERASMUS students and some of them attend mathematics, we developed some materials in English, so they can also use MatActiva. The main objectives of our project are not only to bring success in the subjects of mathematics, but also to motivate the students, encourage them to overcome theirs difficulties through an auto-study giving them more confidence and improve their relationship with the mathematics as well as the communication between students and teachers and among students.

- Matemática activa - moodlePublication . Torres, Cristina; Babo, Lurdes; Azevedo, Jose Manuel; Lopes, Ana PaulaEsta sessão prática tem como objectivo explorar algumas funcionalidades da plataforma Moodle, familiarizar os formandos com a sua utilização, mostrando as suas potencialidades na elaboração de recursos educativos e a sua aplicação no processo de ensino/aprendizagem, incentivando a produção de materiais de apoio ao ensino da Matemática. Desta forma, os formandos poderão acrescentar à sua disciplina on-line uma nova dimensão de interactividade e promover uma participação mais activa dos alunos Sugere-se que os formandos tragam alguns testes de avaliação ou fichas de trabalho que já tenham realizado, de preferência em formato digital, para que a sessão seja mais produtiva.
- Moodle and multiple-choice testsPublication . babo, lurdes; Azevedo, Jose Manuel; Torres, Cristina; Lopes, Ana PaulaMultiple-Choice items are used in many different kinds of tests in several areas of knowledge. They can be considered an interesting tool to the self-assessing or as an alternative or complementary instrument to the traditional methods for assessing knowledge. The objectivity and accuracy of the multiple-choice tests is an important reason to think about. They are especially useful when the number of students to evaluate is too large. Moodle (Modular Object-Oriented Dynamic Learning Environment) is an Open Source course management system centered around learners' needs and designed to support collaborative approaches to teaching and learning. Moodle offers to the users a rich interface, context-specific help buttons, and a wide variety of tools such as discussion forums, wikis, chat, surveys, quizzes, glossaries, journals, grade books and more, that allow them to learn and collaborate in a truly interactive space. Come together the interactivity of the Moodle platform and the objectivity of this kind of tests one can easily build manifold random tests. The proposal of this paper is to relate our journey in the construction of these tests and share our experience in the use of the Moodle platform to create, take advantage and improve the multiple-choices tests in the Mathematic area.
- Multiple-choice tests: a tool in assessing knowledgePublication . Azevedo, Jose Manuel; Lopes, Ana Paula; babo, lurdes; Torres, CristinaThe purpose of this paper is to analyse if Multiple-Choice Tests may be considered an interesting alternative for assessing knowledge, particularly in the Mathematics area, as opposed to the traditional methods, such as open questions exams. In this sense we illustrate some opinions of the researchers in this area. Often the perception of the people about the construction of this kind of exams is that they are easy to create. But it is not true! Construct well written tests it’s a hard work and needs writing ability from the teachers. Our proposal is analyse the construction difficulties of multiple - choice tests as well some advantages and limitations of this type of tests. We also show the frequent critics and worries, since the beginning of this objective format usage. Finally in this context some examples of Multiple-Choice Items in the Mathematics area are given, and we illustrate as how we can take advantage and improve this kind of tests.
- A new approach to numerical algorithmsPublication . Lopes, Ana Paula; Pascoal, António JoséIn this paper we developed a new Lanczos algorithm on the Grassmann manifold. This work comes in the wake of the article by A. Edelman, T. A. Arias and S. T. Smith, “The geometry of algorithms with orthogonality constraints”
- O projecto matactiva no ISCAPPublication . Torres, Cristina; Lopes, Ana Paula; Azevedo, Jose Manuel; babo, lurdesA partir do ano 2007/2008 todos os cursos do ISCAP foram adequados ao Processo de Bolonha, o que pressupõe várias mudanças a nível dos papéis do professor e do aluno, das metodologias e da avaliação. A carga horária semanal das disciplinas da Matemática foi bastante reduzida, por isso foi necessário desenvolver novas estratégias e metodologias de apoio ao aluno. Para complementar as aulas teóricas e práticas desenvolvemos um projecto com o nome MatActiva baseado na plataforma Moodle, disponibilizada pelo PAOL (Projecto de Apoio On-Line). O Moodle permite usar a linguagem TEX para criar materiais que utilizam símbolos matemáticos. Fazendo uso desta funcionalidade, criámos um conjunto de recursos interactivos de fácil utilização. No MatActiva os estudantes têm acesso a um conjunto diversificado de materiais: apontamentos teóricos que lhes fornecem, não só os pré-requisitos necessários para as disciplinas de matemática, mas também material de acompanhamento aos respectivos programas. Para isso, criaram-se vários recursos sendo os testes de escolha múltipla os mais procurados pelos alunos. Estes testes podem ser realizados e corrigidos on-line e para cada resposta errada existe um feedback de resolução. Como o ISCAP recebe alunos ERASMUS e estes frequentam a disciplina de Matemática, foi também desenvolvido material em inglês. Os principais objectivos do nosso projecto são motivar os alunos, encoraja-los a superar as suas dificuldades de uma forma autónoma, permitindo-lhes aumentar a sua autoconfiança e gosto pela aprendizagem da Matemática, assim como fomentar a comunicação professor-aluno e aluno-aluno.
- Teaching with Moodle in higher educationPublication . Lopes, Ana PaulaNowadays, with the use of technology and the Internet, education is undergoing significant changes, contemplating new ways of teaching and learning. One of the widely methods of teaching used to promote knowledge, consists in the use of virtual environments available in various formats, taking as example the teaching-learning platforms, which are available online. The Internet access and use of Laptops have created the technological conditions for teachers and students can benefit from the diversity of online information, communication, collaboration and sharing with others. The integration of Internet services in the teaching practices can provide thematic, social and digital enrichment for the agents involved. In this paper we will talk about the advantages of LMS (Learning Management Systems) such as Moodle, to support the presential lectures in higher education. We also will analyse its implications for student support and online interaction, leading educational agents to a mixing of different learning environments, where they can combine face-to-face instruction with computer-mediated instruction, blended-learning, and increases the options for better quality and quantity of human interaction in a learning environment. We also will present some tools traditionally used in online assessment and that are part of the functionalities of Moodle. These tools can provide interesting alternatives to promote a more significant learning and contribute to the development of flexible and customized models of an evaluation which we want to be more efficient.
